you sure it's superdrol? should be oral masteron.. dht derivative and non-aromatizing.
superdrol is about 2.5-3x the cost of other orals (dbol/drol/winstrol) to produce (superdrol, proviron, var, ect.. are all the same price).
if var is faked with combo's of dbol and winstrol, I can easily see superdrol being faked with winstrol and dbol as well.. even drol.
